BARREL-WASHING MACHINE.

iuasaooe.

To all whom it may concern:

Be it known that I, ARTHUR J. SUHM', a citizen of the United States, residin .at Milwaukee, county of Milwaukee, and tate of Wisconsin, have invented new and useful Improvements in Barrel-Washing Machines, of which the following is a specification.

My invention relates to that type of barrel washing machines in which the barrels are conveyed in a series of step by step movements to various stations at which washing devices are located, some of which wash the exterior and some the interior of the barrel, and which are adapted to cooperate with each other in thoroughly cleansing the barrel.

The objects of my invention are to providea form of barrel feeding mechanism which is capable of operation" in.a small space to feed barrels from a runway which may be transverse to the line of barrel movement through the washing machine;

. also to provide improved means for handling and manipulating the barrels during the washing. operation; also to provide improved washing mechanism.

Like parts are identified by the same reference characters throughout the several views.

The barrels 1 to be washed are rolled down or along a skid way 2 to the place of delivery to the washing machine. At this point one of the barrels is lifted by a pair of grappling tongs and suspended in an elevated position, while a carrier 3 passes underneath it, and again lifts it independently of the tongs and releases it from the latter. The carrier then conveys the barrel stepby step to various washing stations in a series, and finally delivers it to a receiving run way.

The tongs are preferably operated by hydraulic power. A jack cylinder 5 has a plunger 6 connected to a cross head 7, from which hangers 8 depend and are connected at theirlower ends by a cross bar 9 to which the tongs 10 are pivoted. Each mem ber of the tongs is provided at 11 with a roller l2, which strikes the barrel when the tongs move downwardly and spreads the tongs until the gripping jaws 13 pass over the ends of the barrel, whereupon the tongs will drop by gravity to gripping position against the ends of the barrel. Water is then admitted to cylinder 5 and plunger 6 moves upwardly, thus lifting the barrel. During this upward movement, cross bar 9 enters a channel 15 in guide member 16 which holds it in or swings it to,-its proper position with the barrel transverse to the carrier 3. In the construction shown, the barrels are thus rotated a one quarter turn. The curve of channel 15 will of course determine the movement, and the curve of the channel will therefore conform to the requirements of each installation. This lifting movement is suflicient to permit the next barrel to roll under the first one. The side bars of the carrier (hereinafter described) will then be moved to a position partially straddling the second barrel and in a position underneath the lifted barrel, which has in the meantime been rotated a one-quarter turn with its axis transverse to the carrier.

The carrier.

The carrier 3 comprises a pair of side members each composed of upper and lower U bars a and b respectively, (Fig. 2), the outermargins of which are connected by a web 03. The carrier is supported by the plungers of hydraulic jacks, the cylinders 21 of which are vertically disposed. Axle bars 23 are secured to the upper ends of the plungers and provided with wheels 24 which travel in the run ways formed by the upper and lower U-bar flanges a and Z) and the webs d. The carrier is raised and lowered by the plunger movement in cylinders 21 a as water is admitted to and discharged from such cylinders, and a horizontal longitudinal movement of the carrier is also permitted by the wheels 24 upon which the carrier may travel.

To move the carrier longitudinally, I provide it with a downwardly projecting arm 27. Horizontally disposed cylinders 28 and 29, located in front and rear of such arm, are provided with plungers 30 and 31, which bear against opposite sides of this arm. The carrier may therefore be moved forwardly by admitting fluid under pressure to cylinder 28 and rearwardly by permitting such fluid to discharge and admitting it to cylinder 29. The plungers 30 and 31 are provided with rollers 33, which bear upon the depending arm 27 and relieve the friction 'when said arm is moving vertically with the carrier.

The carrier travels in a rectangular path. In Fig. l, the arrow head line 6 indicates the path traveled by the point f on the carrier and therefore this dotted line represents the cycle of carrier movement. From the position in the illustration, the carrier moves vertically downwardly until point f reaches the lower right hand corner formed by the rectangleformed by line e. The next movement of the carrier is horizontally to the left carrying its front end under a raised barrel as above explained, point 7 reaching the lower left hand corner of line e rectangle. The carrier then moves upwardly, lifting the barrel and releasing it from the tongs by spreading the latter. Point 7 is now at the upper left hand corner of the rectangle and the next movement of the carrier is horizontally to the right to the illustrated position, carrying the barrel away from the tongs and permitting another barrel to roll to starting position. This completes the cycle of carrier movement. The front end of the carrier is provided with a tapered spreader member 25 supported from the carrier by arms 26 and adapted to pass between the tongs during forward carrier movement and to spread the tongs during upward carrler movement.

The automatic carrier controller.

The carrier is provided with a controlling member 35 supported therefrom by a post 36. This travels in a rectangular path (corresponding to line 6), along the face of a controller board 37 and operates electrical switches, valve levers or other mechanism adapted to control the delivery of power fluid to the several systems. The drawings illustrate a valve mechanism. In Fig. 5,the valve stems are provided with elbowed operating levers (40 to 47 inclusive), and one arm of each lever is weighted to hold the valve in normal position except when actuated by the controller. In this view, the controller is at the upper left hand corner of its cycle of movement and valve levers 46 and 47 have been actuated from the dotted line or normal position. Valve lever 46 controls the valve in pipe 56, which is the exhaust pipe for cylinder 28, the plunger of which is now extended from its position in Fig. 1. (See Fig. 6). Valve lever 47 actuates the valvein pipe 57, which admits power fluid to cylinder 29. The carrier will therefore move to the right carrying with it controller 35 and during this movement, projection 58 will strike and actuate valve lever to permit power fluid to exhaust through pipe from cylinder 5 and allow the grapple tongs to descend by gravity and engage a barrel.

On completion of the right hand movement of the carrier, the controller strikes levers 40 and 41. Lever 40 admits power fluid through pipe 50 to cylinder 5 to lift the grappler with an engaged barrel and lever 41 opens the exhaust of cylinders 21 through pipe 51. The carrier then descends by gravitv until the controller 35 strikes levers 42 and 43. Lever 42 opens the exhaust from cylinder 29 through pipe 52. Lever 43 admits power liquid to cylinder 28 through pipe 53. The carrier now moves to the left until the controller strikes lever 44, which opens the inlet to cylinders 21 through pipe 54, thus lifting the carrier and completing the cycle of movement from the position assumed in Fig. 5. As all of the valve levers automatically return to normal as soon as the controller moves away fro-m them, it is not necessary to describe these movements in detail. By varying the dimensions of the controller, the degree of carrier movement may be varied.

The washing devices.

porting member 60. The carrier then moves to the right, as above explained, and the barrel is carried .underneath a bung hole finder 61, whereit' occupies the position indicated in dotted'lines in Fig. 1. The carrier then moves downwardly in correspondence with the cycle of movement above explained until the barrel is received uponrollers 63 and continues its downward movement until the barrel rests upon the rollers, whereupon the barrel will be rotated in frictional contact with the rollers. In the meantime, the bung hole finder 61 moves downwardly as hereinafter explained and rests upon the surface of the barrel. The ends of the barrel are held by mechanism hereinafter described, so that the bung hole of the barrel will at one stage of barrel revolution register with the tapered extremity of the bung hole finder 61, permitting the latter to enter the bung hole. This stops the rotation of the barrel.

In the meantime, the carrier 3 will have 'moved toward the left until barrel supporting member 70 is directly underneath the barrel, member 60 being carried underneath the next barrel lifted by the grappler, 10.

The carrier now moves upwardly and mem- 7 ber 70 lifts the now non rotating barrel from the rollers 63, after which the bung hole finder 61 is retracted. The next right hand movement of the carrier in its elevated posi.

tion carries the barrel underneath the initial washer, preparatory to the next downward movement of the carrier. The initial washer comprises a tubular plunger 71 provided with a valve having avalve actuating handle 72. This plunger is received in thecylinder 73, which is in communication with a hot water supply tank 74. The normal pressure of the water tends to force the plunger down but a counterbalance weight 75 tends to hold it up. When the carrier descends, however, mechanism connected therewith, as hereinafter described, depresses plunger 71 and carries the valve nozzle downwardly into the bung hole of the barrel, said bung hole being in position for registry therewith by reason of the operation of the finder: 61. hen the nozzle enters the bung hole, the barrel adjacent to the nozzle strikes the valve handle 72 and opens the valve, permitting hot water from tank 7 1 to discharge forcibly into the barrel, the water being supplied'to tank 74 under pressure.

Fig. 13 illustrates the means for operating the bung hole finder 61 and the plunger 71.

Bung hole finder 61 moves downward under pressure of the liquid in the same manner as plunger 71. When the carrier opens the liquid controlling valve at 271, the liquid enters the cylindrical chamber in which the bung hole finder operates and the latter moves downwardly in the form of a plunger. The operation is exactly the same as that of the plunger 71. The liquid enters and exhausts from the point where the controlling valve 271 is located, the depending exhaust pipe being illustrated in Fig. 13. A fragment of pipe 270 is also illustrated in Fig. 1. The liquid passes through pipe 270 to enter the cylinder and exhausts from the cylinder through the same controlling valve 271. p

In the meantime, carrier 3 moves downwardly far enough to allow the barrel to pipe back to the rest upon a stationary support 76, after which the carrier 3 moves to the left and again rises and receives the barrel upon barrel supporting member 77. During this upward movement of the carrier, plunger 71 is lifted more rapidly than the carrier, as hereinafter explained, withdrawing the plunger from the barrel preparatory to the next rearward or right hand movement of the carrier, which conveys the barrel to the position of member 77 in Fig. 1. During the next cycle of carrier movement, the barrel is merely placed upon stationary rests 78, where it remains until picked up by barrel supporting member 80, which conveys it into registry with a set of washing brushes 81, 82, and 83, for scrubbing its sides and ends.

As the carrier again moves downwardly, brush 81 also moves downwardly into contact with the barrel, brushes 82 and 83 move inwardly into contact with. the. ends of the barrel, and the barrel continues to descend until it rests upon rollers 84. which are driven from the, roller 85 in a manner similar to the manner in which the rollers 63 are driven. The roller 85 is mounted upon a driving shaft 86, (which is provided with a driving pulley 87), and from which sprocket chain 66 leads for the operation of rollers 63. During the period of carrier depression, the barrel is rotated By the rollers 84, causing a relative travel of the brushes 81, 82 and.83 upon its outer surfaces. The barrel having previously been wet and steamed by steam from the hot water delivered through the nozzle plunger 71, its outer surface will be thoroughly cleansed by the action of the brushes. Additional jets of water may be discharged against the barrel if desired, from stationary nozzles 89. While the barrel is being rotated and swept by the brushes, the carrier moves toward the left, then rises and lifts the barrel from rollers 84, and the brushes, having been retracted as herein after explained, the barrel may then be again moved rearwardly by the barrel sup porting carrier member 90 to the next station. At this station, the barrel is readjusted with the bung hole at the bottom.

To accomplish this, a set of rollers 91, 92 and 93 are employed, rollers 91 and 92 being driven from rollers 93 and rollers 93 by a sprocket chain 95 from shaft 86. The shafts 97 of the rollers 91 and 92 extend through suitable bearings in a bar 98, which station where it is again depressed and received by a stationary rest111. A nozzle 113 extends upwardly through this rest in a position to enter the bung hole, and a valve stem 114 controls the water delivery through the nozzle past a valve 115. The weight of the barrel depresses valve stem 114! and automatically turns on the water as soon as the nozzle has entered the barrel. The nozzle 113 is provided with a slotted delivery opening adapted to discharge the water in fan shaped sheet, whereby all parts of the barrel will be reached.

The barrel supporting carrier member 120 then picks up the barrel, conveys it rearwardly and depresses it into registry with nozzle 121, where the washing operation is repeated, said nozzle being located upon a rest 122 and provided with a controlling valve stem 123, the construction being the same as that at the previous station.

The barrel supporting carrier member 130 then -lifts the barrel from rest 122 and conveys it to a position where the next downward movement deposits the barrel upon run way bars 133. The next rearward or right hand movement of the carrier brings the ends of the carrier bars against the barrel and delivers it rearwardly along the run way out of the path of the carrier movement. The run way bars 133 are slightly inclined, permitting the barrel to roll to any suitable point of delivery. The front ends of these bars, however, are preferably slightly recessed at 136 to allow the barrel to remain at rest upon the run way bars until struck by the rear ends of the carrier bars, thus allowing an interval for drainage before the barrel is rolled from its position with the bung hole down.

Barrel alining and washer adjusting mechanz'sm.

At each station where a bung hole finder or washing device is located, means are provided for holding the ends of the barrel to prevent it from moving longitudinally. In each case, the mechanism for accomplishing this is similar to that employed at the station occupied by bung hole finder 100 and which is illustrated in Figs. 2 and 8, Fig. 2 showing the carrier in a depressed position and Fig. 8 showing it in an elevated posi tion. Rods 140 are supported from the car rier on each side thereof by ears 141. Links 142 are loosely connected with these rods and the lower end of each of these links is connected with the frame by a link 144. Another link 145 is pivoted to the lower end of link 142 and its outer end is in slotted pivotal connection at 146 with a'swinging arm 147, the lower end of which is pivoted at 148 to a frame bracket 149. The swinging arm 147- is provided with an elbowed upper end portion 150. The links 144 and 145 form a toggle jointed member to which link 142 is connected. When the carrier moves downwardly, each of these jointed members is actuated to draw inwardly upon one of the swinging arms 147, causing these arms to move inwardly from each side into contact with the respective ends of the barrel and striking the barrel substantially at the center of its head. This accurately centers the barrel upon the carrier and prevents it from moving transversely thereof and holds it in such position that'the bung hole finder 100 will register with the bung hole when the barrel has been rotated to bring the bung hole to the under side. Similar mechanism is employed at the station occupied in Fig. 1 by barrel supporting member 60.

Similar mechanism is also employed for actuating the brushes 82, and 83, (see Fig. 7). At this station, links 152 are connected with a sliding rod 140 and transmit motion through toggle members 154 and- 155 to swinging arms 157, with which the brushes have jointed connection at 158. Brush 81 is supported by a link 160 from a swinging arm 161 pivotally connected with the frame and actuated from carrier rod 140 by upwardly extending link 162. The several levers, toggle members and arms are so connected as to impart the desired motion to the brushes and to the barrel positioning members at the other station, the brushes 81, 82 and 83 being brought in contact with the barrel substantially at the completion of its downward movement. By slotting link 162 at 164, the brush 81 is allowed to adjust 1tself to barrels of different diameters. I do not, however, limit the scope of my invention to any specific means for operating this nozzle member, the brushes or the barrel alining members. The nozzle member 71 and the brush 81 may, if desired, be operated by hydraulic power in the same manner that the grappler 10 is operated.

The object of rods 140 is to allow the horizontal carrier movements without affecting the adjusting mechanism above described. The links 142, 152 and 162 may be -held against longitudinal movement by forked uides 168 as shown in Fig. 7. The rods'140 side freely in their respective bearings in these links during. the forward and back or horizontal carrier movements.

Referring again to Fig. 1, it will be observed that a housing 175 is employed,

' which has openings at 176 and 177, through its . which the carrier and the barrels pass. This housin constitutes a steaming room, since it ten s to retain the steam developed from the hot water which escapes through the nozzle plunger 71. A partition shield 178 is located in the upper portion of this chamber and a steam withdrawing fan 179 has its inlet connected to the cavity 180 above this shield. The fan. suction draws. the steam upwardly and outwardly in the steam chamber and around the outer margins of the partition shield 178, whereby the three barrels which will ordinarily be in this chamber upon members 60,70 and 77, will all be reached by the steam, but said steam will be prevented by incoming air currents from passing through the openings 176 and 177 to an annoying extent.

It-will be observed in Figs. 1 and 2, that a tank 180 is employed to receive water from the barrel'washing or rinsing nozzles 113 and 121. This water may be withdrawn from the tank by a pump at 183 and discharged through a pipe 184 in the form of a spray upon the outer surfaces of the barrel in the steam chamber formed by the housing 175. The connecting rod 186 of the pum may be operated from a crank shaft 18 upon which the rollers 93 are mounted. Another trough 190 is employed underneath the brushes.- 81, 82 and 83. This receives dirty water which is discharged through a drain opening 191.

Water under pressure is supplied to the several cylinders of the actuating mechanism by means of a. high pressure pump at 200. The main actuating shaft 86 is provided with a crank 201 at one end of which the connecting rod 202 is attached. This pump draws water from a tank 205 and discharges it into a closed tank 206. (See Fig. 6). From this tank, water is delivered to cylinder 28 through pipe 210, when valve lever '43 1s actuated; The liquid is discharged from cylinder 28 through pipe 56 into tank 205,

when valve lever 46 is actuated. The connections between tank 206 and the various other hydraulic jacks. above described are similarto those illustrated in Fig. 6 and are therefore not illustrated-in detail. These pipes are broken away in Fig. 1 in order that the other worln'ng parts of the machine may be more c early illust ated. I

It is desirable that the nozzles 113 and 121 be rotated in order that the Water discharged in the form of a fan shaped sheet from these nozzles may be forcibly delivered against the walls of the barrel at the sides, top and ends. 'Any suitable mechanism may be employed for rotating these nozzles, but I preferably employ a Water driven turbine 215. The water discharged through the nozzle serves as power water to also drivethe turbine. The water passes through the turbine in the same manner as in al ordinary turbines. The water is turned on and off automatically by means of a spring supported stem 114, which is depressed by the barrel, and the motion of which is trans mitted to a valve actuating lever. 217 through link 218, lever 219 and link 220. The lever 217 controls a valve 222 in the supply duct 223. A screw 225 provides a plolnt bearing for the turbine rotor and serves as a means for adjusting the rotor into contact with a packing at 226, which prevents leakage. The packing prevents the water from passing from the turbine chamber upwardly between the nozzle and the sleeve bearing in which it is located, said sleeve constituting a part of the turbine casing. The water passes to the interior of the nozzle from between the blades of the turbine 215, said blades being located between the upper and lower disk shaped walls of the turbine. To prevent the turbine from rotating too rapldly, the rotor is provided with projections 230 and thecasing is provided with stationary PIOjGCtlOIlS 231.

The stationary projections resist the circular movement of the water and the water resists and checks the rotatlon of the pro ections 230.

Modified forms of construction.

If desired, a hydraulic jack 235 may be located between the barrel supporting skids p of the skid way 2 underneath the barrel, as

swinging the arms 147 as shown in Fig. 2,

it may be desirable to use hydraulic power for this purpose, as'shown in Fig. 11. In

such case, a single cylinder 240 may be employed, which has a plunger 241 in each end thereof, and each plunger is directlyconnected pivotally Wlth one of the arms-147,

11) shown in Fig. 10. A plunger 236 carries a barrel supporting member 237 on its'upper end and a guide 238 is adapted to rotate the plunger a one quarter turn when the The arms are simultaneously moved outwardly when liquid is admitted to this cylinder 240, while the inward movement will occur by gravity whenever the liquid is permitted to exhaust from the cylinder, the arms 147 being provided with weights 245. Similar weights may be employed on the arms 157 shown in Fig. 7, and the arms 147 shown in Figs. 2 and 8, in order that the barrels may not be crowded longitudinally in either direction by these inwardly moving arms. An equalizer may be provided in order that the movement of one arm 147 may be exactly equal to that of the other. This equalizer will be found useful wherever it is desired to regulate the inward movement of oppositely acting barrel positioning arms. This equalizer comprises a toothed member or gear wheel 250 and rack bars 251. Each rack bar is in mesh with the wheel 250 and is pivotally connected with one of the arms 147. One rack bar meshes with the wheel at the top and the other at the bottom, so that the movement of the bars will be in the opposite direction.

In place of the brush actuating mechanism shown in Fig. 7, it is also possible, and perhaps desirable, to substitute hydraulic power, as shown in Fig. 12. A cylinder 260 receives the power fluid and actuates a plunger 261, upon which a brush 83 is mounted. When the power fluid is permitted to exhaust from the cylinder 260, the brush is retracted by a weight 264, operating through a flexible connection 265, which, if the cylinder is horizontally located, will be passed over a pulley 266. The brush 81 may be similarly actuated from a vertically disposed cylinder.

Referring to Fig. 13, it will be observed that hydraulic means are provided for actuating the initial washer or filler 71. The fluid from tank 74 is conducted to the filler cylinder 73 through a pipe 270, provided with a valve at 271 having an actuating lever 272 adapted to be operated by the controller. It will of course be understood that the power fluid may be applied to the hydraulic jack cylinder 235, arm actuating cylinder 240, and brush actuating cylinders 260 in a similar manner, the controller 35 being utilized.

In Fig. 1, the controller board 37 and con troller 35 are illustrated on a reduced scale as compared with the other parts illustrated in said view. It will of course be'understood that this controller board and controllerare of such size and proportions as to secure the desired carrier movement.
